Polymer Racing Products introduces the worlds first carburetor spacer featuring Dimple Technology. Dyno testing shows the Polymer Racing Products carburetor spacer with Dimple Technology has shown as much as 28Hp & 30ft-lb gain compared to a very popular four hole smooth tapered CNC machined aluminum spacer of same thickness. See below for dyno results.
The increased performance is a result of dimples delaying laminar flow separation which results in drag reduction in the intake path. The delay in laminar flow separation is causes by a phenomenon know as boundary layer turbulence which acts like a suction. A secondary effect is promotion of better air fuel mixing in the turbulent boundary layer. Learn more about Dimple Technology by clicking here.
The polymer material is also 1000 times less thermally conductive than aluminum which means it acts like a thermal break keeping the carburetor cool. This means cooler air flowing to the engine, which means more power.
The cover is made with a carbon fiber impregnated polymer for maximum strength and rigidity. The spacer features aluminum sleeves at the mounting locations for maximum strength for mounting. The carb spacer also features a honeycomb internal structure allowing for a very rigid structure yet being as light as possible.

Compared to a smooth finished 4 hole tapered 1" spacer the PRP 4150 1" spacer shows a net gain of 30 lb-ft of torque at 5000 rpm. Continues to hold significant gain in torque all through the RPM band.
Compared to a smooth finished 4 hole tapered 1" spacer the PRP 4150 1" spacer shows a net gain of 28 Hp at 5000 rpm and continues to hold 10 to 15 Hp gain all the way up to 7000 rpm.
